Kgstewar,
If memory serves me, the first Bonzinis hit the US in 1970 and I believe 400 tables was the quantity that arrived then. Those would likely have been produced in the late 60's-1970. I would bet it was a typo, in the late 60's there wouldn't have been any Bonzinis here to copy. How are you able to date the table to the late 60's? And of course, nothing beats a picture to get better feedback.
